Timer

Overview

The Timer Component triggers at a specified interval, sending periodic messages based on the configured time delay. The first message is sent immediately when the flow starts, followed by scheduled ticks at regular intervals.

Usage

This component is used for time-based automation, such as polling, scheduling, and recurring execution in workflows.

Output Ports

Port	Description
out	Emits a message at the defined interval.

Output Properties

Property	Type	Description
lastTick	string	The last execution time (ISO 8601 format).
now	string	The current execution time (ISO 8601 format).
elapsed	integer	Time elapsed (in milliseconds) since the last execution.

Properties

Property	Type	Description
interval	integer	Execution interval in minutes (min 5, max 35000).

Processing Logic

1. Immediate Trigger: Sends an initial message immediately upon starting the flow.

2. Recurring Execution: The timer schedules and emits messages at the defined interval.

3. Crash Recovery: Ensures messages are not lost in case of system restarts by handling state recovery.

Notes

• Minimum Interval: The smallest allowed interval is 5 minutes.

• Ensured Execution: The component ensures that a tick is processed, even after a system restart.

• Long Interval Support: Supports intervals up to 35000 minutes (approximately 24 days).

This component is ideal for workflows requiring periodic execution, such as polling APIs, running background tasks, or time-based automation.
